If your battery doesn't last as long as it used to, then you likely just need a battery replacement.

We are proud to now offer battery replacement kits for the iPhone 3GS battery. The tools and instructions we send you are all you'll need to make battery replacement a breeze. If you're not the technical type - don't worry, because you can still send the iPhone to us for replacement!

Our 1200 mAh lithium-ion polymer battery is the same strength as the one that came with your iPhone 3GS. It provides 30 hours of music, 10 hours of video, 12 hours of talk on 2G, 5 hours of talk on 3G, 9 hours of internet on wi-fi, 5 hours of internet on 3G or 300 hours of standby between charges. This is a conservative estimate, as we'd rather under-promise and then over-deliver (that being said, we regularly receive feedback from our customers reporting even longer playtimes).

This battery is guaranteed for ten years, so if it ever fails to keep a full charge during this period of time, let us know and we will give you a new one (if you purchased it to install yourself) or re-install one for you (if you sent your device to us for the installation) at no additional charge! No other website offers this kind of coverage.

Look at the power and value this battery provides for your iPhone 3G:

We offer a variety of same-day shipping options from us to you, perfect for any level of urgency.

First of all, I looked all over the place for a new battery for my iPhone, and I couldn't find anything. I was just about to give up, but a friend of mine recommended me to this company. She had used them before to fix her iPhone battery, and she has been happy ever since. One of the main reasons I decided to check out this company was because they offered a 10 year battery guarantee, which I literally know that you can't find anywhere else. This was a very fast service, and I initially was thinking that it would take much longer than it did. I was nervous about being without my iPhone for a while, but Milliamp got it back to me right away!

My iPhone would intermittently die at any battery level when I'd place load on the processor. It was about 18 months old. I ordered a replacement battery from here and it promptly arrived a few weeks later (cheap overseas delivery option). I used the instructions here: to change the battery and it's now working like a dream! Just as good as when it was new. I'm very satisfied and would recommend milliamp to everyone. As the other reviewer rightly puts, you'll be hard pressed to get better warranty terms elsewhere.

This is the second replacement battery for my 3GS. The first one was purchased on the cheap from another website. i was not happy with the performance, the battery would not charge to 100% and would run out of battery by around 28%. in the end you get what you pay for.
The Milliamp battery performs much better. the installation instructions are accurate and easy to follow. shipping was fast and payment easy. Good job milliamp... will definitely buy from you again!

I bought 2 batteries for my 3GS and then Apple upgraded the firmware and stopped my phone from working. The milliamp battery works with the new firmware and it came with the proper tools. Highly recommend!

When I upgraded my 3Gs to os 4.3.2, I encountered error 29. After searched many websites, I accidentally found this website. At first I was hesistant to buy online, but because no local seller had 3ga battery I ordered from milliamp. After less than 2 weeks, my battery arrived. Now, my phone have come to live and running again. Many thanks for the customer service and bonus tools for opening my phone. Definetely recommended for anyone to buy from milliamp!

Feedback From Our Customers

Just wanted to say thanks! I've had to wade through a sea of cheap, overrated (literally) knock off replacement power cells to find yours works great. You provided a great kit at a great price and breathed new life into my ailing iPhone 3GS. Big thumbs up! Thanks guys,

Helpful Battery Replacement For The iPhone

I use my iPhone for so many daily tasks that it is not even funny. Let me walk you through my day. First of all, I use it as my alarm clock, and I just threw away my old alarm clock. My old clock would never wake me up on time, and now I can use my iPhone to get me up right away. Next, I will normally check the weather with my iPhone app to see what I need to wear for that day. I feel like I am so technologically advanced because I can use my phone to tell me what to wear! After that, I will listen to music on my iPhone while I ride the train to work, which keeps me relaxed and refreshed. Throughout the day, I travel to many different departments within my work, and I use my iPhone to check my e-mail and stay updated with my supervisor. If I'm going to lunch, I will normally use Urban Spoon on my iPhone to see where I want to eat in the area. As you can see, my iPhone is completely vital to me, but it doesn't stop there! I again will listen to music or play apps on my iPhone, and I will also look up a recipe on my iPhone to make dinner when I get home. If my husband is watching TV in the evening, then I will either play apps or watch a movie that I have downloaded on my iPhone. I seriously use it so much that my husband jokes that I'm going to break it! I guess all of this use has definitely run down the battery because my iPhone will not charge as much as it usually does. I decided to look online to see if I could purchase a new battery to keep it running in tiptop shape, and I found a company that was able to change it out for me. I was so happy to find this service that I sent my iPhone in to them right away to get it taken care of. This company offered me a very affordable battery replacement, and they actually guaranteed it for 10 years, which was really impressive. My husband also has an iPhone, and he was thinking that he was also going to get his battery replaced since it was not working as well as it was when he bought it. We were both very happy with this service, and we will be recommending it to all of our family members and friends. This is something that I wish that more people knew about because I had never heard of replacing a battery on an iPhone before this time!
